Ruling on exchanging gold for gold with an increase

Question:
If a woman wants to exchange her gold for other gold, must she first sell her gold, take possession of its price, and then buy the other gold? Or is it permissible for her to take other gold by weight, paying an additional amount if required?

Answer:
She should sell it first, then buy. However, if it is an exchange of gold for gold, weight for weight, like for like, hand to hand, there is no harm. If she finds gold that suits her, and she has gold to give to the owner of that gold, and their weights are the same, there is no harm, hand to hand, like for like.
But if the gold differs in weight, she is not allowed to do that. Rather, she must sell it for silver, or for other goods, and then buy the other gold. This is based on the saying of the Prophet (peace and blessings be upon him): Therefore, she must sell the gold, then buy the other gold with silver, or with another currency, or with other goods, such as clothing, food, and the like.
As for gold, no, except weight for weight, like for like. And if she sells it for silver, there is no harm, hand to hand.
